MA732GQ-Z from Monolithic Power Systems, in a QFN-16(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SSD | output | SSI serial data output. Streams the absolute angle over the SSI-style synchronous serial interface clocked by SSCK. |
| 2 | A | output | Incremental encoder A channel output (ABZ quadrature). Pulses per turn programmable from 1 to 1024. |
| 3 | Z | output | Incremental encoder Z (index) channel output, once-per-revolution pulse of the ABZ quadrature interface. |
| 4 | MOSI | input | SPI data input (master out, slave in). Has an internal pull-down resistor. |
| 5 | CS | input | SPI chip-select, active low. Has an internal pull-up resistor. |
| 6 | B | output | Incremental encoder B channel output (ABZ quadrature), 90 degrees out of phase with channel A. |
| 7 | MISO | tri_state | SPI data output (master in, slave out). Has an internal pull-down resistor that is enabled while the pin is in the high-impedance state. |
| 8 | GND | power_in | Supply ground reference. |
| 9 | PWM | output | 14-bit PWM angle output. Typical PWM frequency 970 Hz (840-1090 Hz). |
| 10 | TEST | input | Factory use only. Must be tied to ground in the application. |
| 11 | MGL | output | Digital diagnostic output that asserts when the sensed magnetic field strength falls below the programmable MGLT threshold. |
| 12 | SCLK | input | SPI serial clock input. Has an internal pull-down resistor. |
| 13 | VDD | power_in | 3.3 V supply input (3.0-3.6 V). Typical supply current 11.7 mA. Decouple with 1 uF to GND. |
| 14 | NC | unconnected | No connection. Leave unconnected. |
| 15 | SSCK | input | SSI serial clock input for the SSD data-out stream. Has an internal pull-down resistor. |
| 16 | MGH | output | Digital diagnostic output that asserts when the sensed magnetic field strength rises above the programmable MGHT threshold. |
| 17 | PAD | power_in | Exposed thermal pad on the bottom of the QFN-16. Connect to GND for thermal and mechanical reliability. |
